I have a HL-DT-SD DVD RW GSA -H31L W616 125 lightscribe drive. I have bought HP CD's and it ejects about 70% of them. When it does burn it burns fine. I have tired cleaning the disc as instructed but it still doesn't work. I have lightscibe system software version 18.104.22.168. It wont read any Polaroid disc as well. Is this an issue with the drive or a firmware issue?
